Speciihmtion of Letters Patent.

Application nica January 5,1914. serial No. 810,476.

clare that the following description of my,

said invention, taken in connectionwith the accompanying sheet of drawings, forms a full, clear, and exact specification, which will enable others skilled in the art to which it appertains to makeland use the same. l

This invention relates generally to improvementsin closet'seats, and it consists,

essentially, in the novel and peculiar combination of parts and details of construction, as hereinafter rst fully set ,forth and described and then pointed but in the claim.

In the drawing already referred to, which serves to illustrate my, said invention more fully, Figure 1 is a plan of a rectangular wood blank,parts being broken away to 4show the several layers of veneer compris-l ing said blank. Fig. 2 is a section in lineA 2 2 of Fig. 1. Fig. 3 is a plan of the said blank sawn to approximate outline to produce the core of .a water closet seat comprising my invention. Fig. 4 is a plan of the blank after being machined and turnedl to produce the seat core, said plan showing pubescent surfaces produced in the process of machining for purposes'phereinafter 4described. Fig. 5 is a cross section inline 5-,5 of Figgll on an enlarged scale. Fig. 6 isa section in line 6 6 of Fig. 4 on an enlarge-d scale, showing the same as being covered with a fine, hard rubber veneer.l Fig. 7 is a similar cross section illustrating a seat having a concavo-convex cross section, this conformation being preferred when an especially light weight seat, is a desideratum. I

Like parts are designated by corresponding symbols or characters 'of referencev in all the figures of the drawings.`

One of the greatest sanitary necessities of the present day, particularly andespecially with respect to public comfort stations, hotel and public toilet rooms, and, in fact private bath rooms, are water closet seats which are unbreakable and sanitary 1n every respect; seats in which there are no crevices of any kind for the receptionA of germ generating matter, and whose outer surfaces are Patented Julyz's, 191s.

positively immune from germ impregnation,

Such seats, to be a success, must always remain sweet and must be of such a nature that fecal matter deposited. thereon may easily be removed therefrom without affecting the outerinish thereof.

The only material whiclfpossesses the qualities of not being affected by moisture, the

action .of uric acids, or excrementitious matter is fine, hard rubber. But, `a seat made purpose specified, is prohibitive'in'cost.

Therefore, the object of my: invention is the construction of a sanitary water closet seat in which all the preeminent qualiyties 'of a fine,- hard rubber seat are retained,

which is capable of as high a polish, vand is as able to retain the same under service, at a price which will enable 1t to be sold 1n competition with theaverage types of wooden seats.

To secure this result I/prepare a wooden blank B which is built up from a plurality of layers of-sheared wood veneer 1, 2, 3, 4 and 5. This veneer averages about 2; thick and is ofthe cheapest'grade of lumber, such as gum wood, cotton wood, bass wood, and the like. sawn to rectangular outline of a size that a seat blank may be sawn therefrom, and every sheet is first kiln dried, after which I apply a thin layer of heat and moisture proof glue or cement toeach sheet'and build up the blank B, the grain -of each successlve sheet being disposed a-ngularly. to .the grain of the preceding sheet'asclearly seen at 6,

7, 8, 9, and 10, Fig. '1. After `the blank is built up, the 'same is placed 1n a suitable press and the layers ofi veneer comprlsrng, the same squeezed together under great pressure, so as to secure perfect 'contact of all the surfaces with the nement. A'fter the cement is set, the completed blank 1s agaln -placed in a drying kiln under pressure and so super-kiln dried thatthe last vestigeI of moisture4 has been expelled therefrom.

The blank B is next sawn to anoutlme approximately the external contour of,l

i from this material, while being ideal for the These sheets of veneerv are thereof is such as Yto produce a pubescent surface D throughout the surfaces of the core, leaving the same with a rough, grooved pubescent surface. Said core 1s machined somewhat smaller than the finished seat is to be, and is now ready for its exterior veneer of ne hard rubber.

It will now be observed that the core being built up in layers, of wood veneer, the grain of each successive layer of which is disposed angularly of the grain of the preceding layer, the whole so thoroughly kiln dried as to be devoid of moisture, a seat core is produced which is as near unbreakable as it is possible to manufacture such an article. And combined with-this there is a. lightness of weight not otherwise obtainable.

A sheet of semi-plastic fine rubber is now pressed into-shape in a proper mold, and the aforesaid core is placed within said sheet,

I with a fiat sheet of semilastic line rubber placed over the core. 'T e mold is closed, placed in a press and great pressure applied, forcing the semi-plastic fine rubber veneer directly into the faces of the core and causing the rubber material to become anchored,

j as twere, to the pubescent surface hereinbefore mentioned, .thereby causing a double adhesion ofthe rubber veneer to the core. The next process is the placing of the filled mold into a vulcanizer, whereby suitablev curing under heat and pressure, the semiplastic fine rubber is converted into a true vulcanite'or hard rubber veneer E, dense and hard in texture, hermetically sealed within which is the wooden core C above i described.

So great is the adhesion of this hard rubber veneer to the core that if the seat be smashed by means of an ax or like instrud ment the Vulcanite will be found to adhere ough kiln drying of the core, as described,

Arenders the fiberl of the core more easy of penetration by the semi -plastic rubber veneer, and secondly, the pubescent surface of the core proves an additional anchorage for v as the same is of like construction as the seat, but minus the opening O. Neither have 1 illustrated the seat hinges and rubber buffers, as they are of typical construction and are not artof my invention.

It is now to e understood that I may produce my seat in any desired or preferred shape or'conformation.

Having thus fully described my invention, I claim as new and desire to secure to myself by Letters Patent of the United States A closet seat comprising awood core consisting of a pluralltyof thoroughly dried layers of wood veneer arranged one upon the other with the ain of each layer disposed angularly wit respect to the grain of the adjacent layer or layers, said layers being cemented together and said Vcore having a rough pubescent surface, and a covering of hard rubber vulcanized on said core and united therewith throughout the entire surface of the core.

In testimony whereof I have hereunto set my' hand in the presence of two subscribing witnesses.
